FFmpeg software minor modificatn convert mp3 to flv

Please reply with the codeword *easyconvert101* all autobids will be ignored! This is a quick and easy project for a coder who knows what they are doing. I am looking for a coder with skills in ffmpeg modification. Here is a sample file of a program that converts 1000 frames of an audio file (mp3) plus a picture into an flv video [login to view URL] I would like to have a program that can render unlimited audio length and also have a picture to render the video. (that is the task of this tender - please bid accordingly) It will be a minor modification of this program. Can you also give a quote to build a software program with much more features e.g. multiple photos, powerpoint presentations, different audio bitrates and video formats Thanks!
